Multiple vulnerabilities in VMware Workstation and Fusion

1) Use-after-free

EUVDB-ID: #VU89630

Risk: Medium

CVSSv3.1: 7.9 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-22267

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a guest user to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the VBluetoothHCI_PacketOut method in the vbluetooth device. An attacker with administrative access to the guest OS can trigger a use-after-free error and execute arbitrary code with VMX process running on the host.

Mitigation

Install updates from vendor's website.

Vulnerable software versions

VMware Workstation: 17.0 - 17.5.1

VMware Fusion: 13.0 - 13.5.1

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote authenticated privileged user via the Internet.

How the attacker can exploit this vulnerability?

The attacker would have to trick the victim to open a a specially crafted file.

No. We are not aware of malware exploiting this vulnerability.

2) Heap-based buffer overflow

EUVDB-ID: #VU89631

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2024-22268

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the Shader functionality within the SVGA virtual device. A malicious guest with non-administrative access to a virtual machine with 3D graphics enabled can trigger a heap-based buffer overflow and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's website.

CWE-ID: CWE-665 - Improper Initialization

Exploit availability: No

Description

The vulnerability allows a malicious guest to gain access to potentially sensitive information.

The vulnerability exists due to improper initialization within the UrbBuf_getDataBuf function in the vbluetooth device. A malicious guest with local administrative privileges on a virtual machine can read privileged information contained in hypervisor memory from a virtual machine.

Mitigation

Install updates from vendor's website.
